Apple alone doesn’t make a filling meal, even for an iPod. Download
the free iPodWizard, which makes it possible to load third-party
firmware onto your iPod. If things go wrong or you don?t like the
changes, you can return to iPodWizard and click the Downgrade
Firmware button to restore your iPod?s original firmware.
Note: This link takes you to the vendor’s site, where you can download the latest version of the software.
